Description
Current behavior
I use native stack with presentation: 'modal' option. When dragging modal up, it jumps at the bottom once I release. It works fine compared to native iOS applications.
If I switch to @react-navigation/stack (not native) there is no such issue.

Actual issue is at the bottom.
Expected behavior
Comparing to iOS calendar app:

Research direction
Start by reproducing the iOS gesture with @react-navigation/native-stack using the reported package versions, then compare it with @react-navigation/stack and the supplied recordings. Investigate the native-stack and react-native-screens integration involved in modal dragging. Done means releasing the upward drag no longer causes the modal to jump and matches the expected iOS behavior.
